A cron-like time-based job scheduler for Dart

Run tasks periodically at fixed times or intervals.


A simple usage example:

import 'package:cron/cron.dart';

main() {
  var cron = new Cron();
  cron.schedule(new Schedule.parse('*/3 * * * *'), () async {
    print('every three minutes');
  cron.schedule(new Schedule.parse('8-11 * * * *'), () async {
    print('between every 8 and 11 minutes');



  • Fix issues for Dart 2 compatibility.


  • Slightly better handling of the async errors.


  • Initial version.
